INSTALLATION AND DESCRIPTION
(Vented Condensate Units)
DESCRIPTION
Pumps
are float operated to return accumulated condensate to
a boiler feed tank.
Receivers are non-code cast iron or steel.
WARNING: EXPLOSIBLE
Do not
pressurize receiver. Isolate receiver during leak
test. Do not plug overflow. Do not restrict vent opening to
atmosphere. Open valves slowly. Failure to follow these
instructions could result in serious injury or death.
PRELIMINARY INSPECTION
Assure that there is no shipping damage.
Assure that nameplate ratings agree with job specifications and
actual conditions.
HANDLING
Use
care in installing unit.
CAUTION:
UNIT LIFTING EYE
Use unit lifting eyes only to lift unit as shipped
factory. Unit must be empty and disconnected from pipes,
anchors and other restraints. Use proper rigging procedures.
Failure to follow these instructions could result in injury or
property damage.
LOCATION
Place unit for easy access to all parts. Allow adequate space
for servicing. Check ambient conditions.
NOTICE /
TEMPERATURE LIMITS
Motors
are designed to operate in 104ºF. (40°C) max. ambient.
Insulate or ventilate as required.
PIPING (General)
Pipe the unit per the Elementary Piping Diagram. Locate and
support piping so as to not load the pump discharge.

CAUTION:
Inject boiler feed compounds
into boiler feed piping – never into condensate tank. Failure
to follow these instructions could result in injury or property
damage.
PIPING
(Returns)
Gravity
return lines from system should be properly pitched
down to unit inlet. Returns must also be trapped to pre-
vent steam entry into the unit. An inlet basket strainer is
recommended.
PIPING
(Vent)
Install a vent pipe to
on unit. Do not restrict or reduce vent opening or exceed 20
feet vertical height unless an overflow connection is provided.
PIPING (Overflow)
Pipe overflow port to drain using an overflow loop when
densate temperature will exceed 200ºF. (93°C).
FLOAT SWITCHES & MECHANICAL ALTERNATORS
Floats
are locked in place to prevent damage during shipment.
from
Remove shipping locks. Check factory settings. Floats and
mechanical alternators are adjustable for various levels of oper-
ation. The lead pump should start with tank
at 2" or more above pump inlet. Lag pump should start before
the tank overflows. Settings should avoid "short cycling" of the
pump.
ELECTRICAL WIRING & CONTROLS
Connect power wiring per NEC. Recheck nameplate vs.
ifications and conditions. All single phase motors have internal
thermal protection.
WARNING: HIGH VOLTAGE ELECTRICITY
Disconnect and lock out power
servicing unit. Failure to follow these instructions could
result in serious injury or death.
Three phase motors must use starters with properly sized over-
load relays. Overload relays furnished are designed for manual
reset.
NOT A CHEMICAL PUMP
from chemical feed tank
